Next Descent Anti Fog Spray for Swimming Goggles & Diving Mask Defog Solution for Pool, Snorkeling, Scuba and Freediving

My husband and I apply this twice per day while snorkeling. We prefer full mask snorkels - and I also use it when diving. Lasts a long time and provides great clarity under water

I got this my husband. He uses a mask and it kept fogging on him. I have goggles and spit works great for me, but not for him. He said it worked perfectly, no fogging for his whole time swimming. He highly recommends this product.

Works great, spray it, rinse it, use it.

It works well preventing fogs while swimming for my goggles. The only issue I have is that it sprays a lot, and I always have a lot of leftovers. It also hurts when it gets into your eyes, so be careful!

This works great! I didn't experience any eye irritation. I cleaned the glass before every swim prior to applying defog. The mask remained clear for hours of swimming.

Works, but came with no cap/cover and 1/2 was leaking out. Although works well, will try another brand next year they do not know how to pack their product. Rrally sad as when you get enough for the trip it is a great product

We ended up using this only one day while snorkelling in Hawaii, but it was totally worth it. This stuff worked spectacularly! Not a bit of fogging during our outing. I've used anti fog products before, but this one is by far the one that worked best.

Where do I start with the miraculous, life-altering, almost supernatural powers of this scuba diving defog product? As a seasoned diver who's braved the murkiest of waters, I thought I'd seen it all. But then, this little bottle of wonder fluid danced into my life, and BAM! My diving experience transformed forever! I put a drop of this defog elixir on my mask, and suddenly, I'm seeing fish plan their weekend, counting the grains of sand on the ocean floor, and reading the fine print on lost underwater treasure maps! It's like having HDTV strapped to your face underwater. And the lasting power? I applied it once, and I'm convinced it has defogged my life in general. I'm pretty sure it's even cleared the fog of uncertainty in my love life. It’s not just a defogger; it's a window to a clearer, brighter underwater world. Get it, or resign yourself to a life of foggy, mundane dives!

I'd buy these again. Works really well for my swim goggles. Lasts a few swims usually if I just apply it and go swim, but if I let it dry and wait a bit, it lasts about a week. I want to try them on my helmet visor next.

Works great for my swimming goggles

This seems to work, but I don’t know if I would consider it reliable. I found the instructions on the back of it to be a little bit inaccurate. I sprayed a bunch on various lenses and tested them out. I’m still getting a little bit of fog, but for the most part it does work. I was almost gonna return this, but it seems to do good enough of a job in a pinch. I think this it’s pretty good, but I’m not sure if there’s a better option out there. It does work, but depending on what you’re using it for you might have to reapply it often. What I found so far, is if you wipe it in and use a fair amount of it it works quite well. Don’t wash it off right away like the instructions. Tell you to do. Make sure to keep a fair amount on the inside of the lens without the lens getting gunked up and it seems to do a pretty good job. Overall, I’m happy with it, but it doesn’t work quite as well as I would like it too. Still, I think it’s better than nothing and it does help to stop the fog.. enough to be happy with I guess, but not entirely.

Incredible spray. One spray on the inside of the snorkel and it’s clear as a bell. I tried it out for 40 min and it was clear the whole time. I plan to buy more bottles. This is a great size for Travel as well.

Works, but not for long, You have to reapply after every use. When moving, touching or taking off your goggles even for a little bit, will risk fogging up your goggles permanently until you clean it again. I’ve noticed that the spray relies on the heat from your breath, if no heat is present you risk the anti-fog spray FREEZING in your goggles, which isnt “fog” but it does obscure your vision. Overall its ALRIGHT considering the price.
